1149902 - The Reading List's sidebar is sometimes enabled automatically in newly opened private windows

Status: NEW

(Firefox Graveyard :: Reading List, defect, P3)

Description

[Andrei Vaida [:avaida]]

Reproducible on:
* Beta 38.0b1-build1 (20150330154247)
* Aurora 39.0a2 (2015-03-31)
* Nightly 40.0a1 (2015-03-31)


Affected platform:
Windows 7 (x64)

Steps to reproduce:
1. Launch Firefox.
2. Enable the Reading List sidebar, via toolbar → bookmarks menu → Reading List → Show Reading List Sidebar.
3. Add a few pages to Reading List.
4. Open a private window, via menu → New Private Window.

Expected result:
The private windows opened from regular ones do not show the Reading List sidebar.

Actual result:
Intermittently, private windows will sometimes show the Reading List sidebar automatically if it was also enabled in the regular window.

Notes:
- This issue is reproducing *intermittently* so the str mentioned above are not 100% reliable.
- Another issue I noticed is that the automatically opened Reading List sidebar from the private window is missing its header: (screenshot) http://i.imgur.com/BPbMagN.png.
- This issue might be reproducible on other platforms as well, but I didn't yet manage to investigate it further.

I don't see a need to isolate the reader-list - there are valid reasons to choose to view specific sites in PB mode and want to select them via the sidebar.  Maybe we just want a PB window to always open with the sidebar closed but able to be opened?

On Windows 8.1 32bit using Firefox 38 beta 1 (20150330154247), the Reading List sidebar is always enabled (displayed) by default in newly Private Window.

Good suggestion, Mark. That would communicate to the user, a more private experience.
